Seedance 2.0 Fast is BytePlus / Doubao’s new-generation multimodal video creation model. It inherits the core capabilities and strengths of Seedance 2.0 while optimizing for faster generation speed. The model supports using images, videos, and audio as multimodal reference inputs for video generation, and also includes video editing and video extension abilities. It is aimed at more precise generation and iterative reuse in production workflows. Compared with the standard model, Seedance 2.0 Fast focuses more on turnaround speed while still improving physical consistency, real-world alignment, and instruction following for professional storytelling tasks.
